Last night Zoe woke up screaming and crying from a nightmare. She just couldn't calm down, so she ended up in our bed. (Which meant Danny ended up on the couch, because three cannot sleep comfortably in our bed.)
This morning, when asked what the dream was about, she said, "It was a painting nightmare."
"A painting nightmare?"
"Yes! I wanted to paint green, and it kept coming out blue!"
Danny didn't understand, but it made perfect sense to me.
